<span class="bs-stepper-label">Various information</span>
</button>
</div>
</div>
<div class="bs-stepper-content">

<div id="logins-part" class="content" role="tabpanel" aria-labelledby="logins-part-trigger"></div>

You can listen on those events like that:
var stepperEl = document.getElementById('stepper')
var stepper = new Stepper(stepperEl)
stepperEl.addEventListener('show.bs-stepper', function (event) {
// You can call prevent to stop the rendering of your step
// event.preventDefault()
console.warn(event.detail.indexStep)
})
stepperEl.addEventListener('shown.bs-stepper', function (event) {
console.warn('step shown')
})The event detail object contains the following properties:
{
indexStep: contains the id of the step which will be displayed,
to: alias of indexStep,
from: previous step id (or current step id)
}If you need to prevent the display of a step, you have to call preventDefault on the show.bs-stepper listener.
